2, Get appkey (first get the shaw1 value of keystore)

image.png

(1) , find debug.keystore in the directory C:\Users\Administrator.android,

(2) next, enter the cmd command in the address bar of the directory

Absolute path of Keytool -v -list -keystore debug.keystore

(3. Enter the password (the password is android)

(4) copy the shaw1 value

3, Import the jar package and add it to the dependency Library (copy the jar of the 2D map demo to the project)

4, Copy Demo's manifest file
